我有一個問題,willDisplayCell它不會停止從URL中擷取XML 我的代碼:負載多種細胞「willDisplayCell」問題
- (NSInteger)tableView:(UITableView *)tableView numberOfRowsInSection:(NSInteger)section
{
// Return the number of rows in the section.
return [itemsToDisplay count] + 1;
}
- (UITableViewCell *)tableView:(UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *)indexPath {
static NSString *CellIdentifier = @"Cell";
UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];
if (cell == nil) {
cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleDefault reuseIdentifier:CellIdentifier] autorelease];
}
if (indexPath.row == [itemsToDisplay count]) {
cell.textLabel.text = @"Load More...";
} else {
MWFeedItem *item = [itemsToDisplay objectAtIndex:indexPath.row];
cell.textLabel.text = item.title;
}
return cell;
}
- (void)tableView:(UITableView *)tableView willDisplayCell:(UITableViewCell *)cell forRowAtIndexPath:(NSIndexPath *)indexPath
{
if (indexPath.row == [itemsToDisplay count]) {
// Parse
NSURL *feedURL = [NSURL URLWithString:@"http://gdata.youtube.com/feeds/api/users/RayWilliamJohnson/uploads?v=2&alt=rss&sort_field=added&start-index=21&max-results=20"];
feedParser = [[MWFeedParser alloc] initWithFeedURL:feedURL];
feedParser.delegate = self;
feedParser.feedParseType = ParseTypeFull; // Parse feed info and all items
feedParser.connectionType = ConnectionTypeAsynchronously;
[feedParser parse];
[self.tableView reloadData];
}
}
它的樣子,他是實物循環,這並不停止獲取xml
那麼我該如何解決這個問題,我只會打一次電話?
